Troubleshooting
Weigela 'Wine & Roses' problems — and how to fix them
Weigela 'Wine & Roses' (Weigela florida 'Alexandra') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Foliage greening in shade
Insufficient sun fades the signature burgundy leaves toward green and reduces flowering. Relocate to or plant in full sun to keep the dark colour.
Sparse rebloom
The main flush comes on old wood in late spring; light reblooming benefits from deadheading and a prune right after the first flowering, not in late winter.
Powdery mildew
White film on leaves in humid, crowded sites. Space plants for airflow, avoid overhead watering, and remove badly affected growth.
Aphids and spider mites
Sap-feeders distort new shoots and stipple leaves in hot, dry spells. Hose off, encourage predators, and treat only persistent infestations.
